Electric rickshaws give one of the world’s poorest countries a charge

The streets of the crowded tourist city of Kathmandu, in Nepal, are like a slow-moving showroom of the auto industry, with packs of buses, cars, taxis and motorbikes chugging along.

But if you take a closer look, you will find that some of the smaller buses have only one front wheel. They have no exhaust, and they don’t chug. Emblazoned with a sign that says “Save Kathmandu,” they are among the smallest and least-familiar models in the world’s growing fleet of electric vehicles: the battery-powered “autorickshaw.”

Nepal has been one of the lowest nations in the rankings of national economic output, but that has not stopped electric vehicles from finding a peculiar niche. Local businesses have already persuaded more than 100,000 commuters in Katmandu to ride the autorickshaws every day as they pick up passengers on designated routes.

Now they’re beginning to push more advanced electric vehicles into the market for the more knowledgeable and well-heeled buyers. A poster in one of the showrooms says: “Do Not Let Petroleum Hold You Back, Go Electricity Today.”

For the 2.5 million people who live in this area, driving electric vehicles will be liberating in more ways than one. Nepal has no native fossil fuels, so every drop of oil used here has to come from India, which drains Nepal’s limited foreign currency.

“Electric vehicles are important for Nepal,” said Binod Prasad Shrestha, director of the Nepal office at Winrock International, an Arkansas nonprofit organization that supports Nepal’s electric vehicle development.

“It helps with climate change mitigation,” Shrestha said. “Also, we are now spending more on fossil fuel imports than what we make from our total exports.”

When smog came to Shangri-La

“Even though conventional cars are becoming cleaner, the number of cars on the road is making air quality worse,” explained Lloyd Wright, a senior transport specialist at the Asian Development Bank.

By the 1990s, Nepal had already started electrifying its transportation system. At that time, Katmandu, once renowned as Shangri-La for its natural beauty, was enveloped by a smell of diesel, due to vehicle emissions.

To clear the air, in 1993, the U.S.-based Global Resources Institute began an experiment of converting diesel-powered rickshaws into battery-operated ones. Then a group of Nepali engineers, using imported auto parts, produced the more powerful electric three-wheeled autorickshaws. They’re commonly known here as “SAFA Tempo,” or “clean three-wheelers” in Nepali.

The fleet grew from seven in 1993 to 500 in 2005. Meanwhile, an indigenous electric vehicle industry took shape. During the early 2000s, dozens of recharging stations were installed and four assembly factories were built.

But Nepal’s demand for electric vehicles fell shortly after 2005, when the government refused to let electric three-wheelers operate on more commuter routes and began importing diesel-powered minibuses.

‘Lady drivers’ come to the rescue

The Nepali electric vehicle industry blamed its development slowdown on diesel-powered vehicle importers, as well as on corrupt officials who wanted to profit from import taxes and fossil fuels trading. The government denied that, asserting that electric three-wheelers were involved in collisions in which drivers were found speeding.

The electric vehicle owners came up with an inspired political fix: hiring women. The idea was that “lady drivers” would put a gentler hand on the wheel.

Megesh Tiwari, a program official at Winrock International, explained: “They do not go over speed, they take care of the car, and they drive more carefully.” The women created an economic boost.

One of those women, Devi Shrestha, 28, talked about it while taking a lunch break. “My life has changed dramatically after I became a SAFA Tempo driver,” she said.

Shrestha said she used to earn 2,500 rupees ($25) per month for painting furniture. But as soon as she started driving electric autorickshaws in 2007, her monthly income quadrupled.

With a higher income, Shrestha was able to send her children to a better school. She also saved enough money to buy a second electric three-wheeler, which she has leased to another driver.

“So now I’m not just a driver, but also an entrepreneur,” Shrestha said, smiling. She has since trained more than 10 women to be electric vehicle drivers.

According to the Nepal Electric Vehicle Association, women now take the wheel in more than 200 of the electric autorickshaws in Katmandu; the sector employs about 700 drivers. Meanwhile, Nepal’s electric vehicle industry has been lobbying the government to open more routes.

It’s also looking to sell electric vehicles that can run anywhere. Umesh Raj Shrestha, president of Shree Eco Visionary Pvt. Ltd., tried to make battery-powered buses for local travel agencies that promoted ecotourism. After converting his gasoline-powered car to run on electricity, Shrestha started to make such conversions for others.

The government strikes back

But then he hit a policy wall. The Nepali government banned the practice of converting fossil fuel vehicles into electric ones. It also lured Nepal’s tourism industry to purchase fossil-fuel vehicles by offering a tax break for buying them, which electric vehicle buyers don’t enjoy.

Another blow came in 2007: When Shrestha imported electric bicycles from China to Nepal, he found himself unable to sell the 3 million rupees’ (about $30,000) worth of them.

“There was no category for e-bikes in Nepal at that time,” Shrestha explained. He later successfully lobbied the government to set up a new category, but the imported e-bikes were worth almost nothing because their batteries had decayed.

“That was a very difficult time,” Shrestha recalled. “But I’m still a fan of electric vehicles. This is not just a business, but a passion that I am doing something good for the environment and for my country’s energy security.”

Now Shrestha is planning to import auto parts from China and assemble electric minibuses in Nepal. They will be safer and perform better, he thinks, because they are four-wheeled and use new lithium-ion batteries. Currently, Nepal’s electric autorickshaws carry bulky and heavy lead-acid batteries.

Blackouts and salesmanship

Meanwhile, Pramod Bhandari, a dealer of the Indian-made electric car called REVA, is trying to convince private car owners that it’s more stylish and cleaner to drive one.

“Katmandu Valley is a very electric vehicle-friendly place,” Bhandari said. “People here usually travel about 60 kilometers per day, while the electric vehicle can give them 100 kilometers (62 miles) per full charge.”

Some buy the car for its green image, while others do it to appease their wives, who want to avoid long hours waiting in gas station lines. While the cars cost 40 percent more than gasoline-powered cars, he tells buyers they will recover the extra cost within five years.

Sales have picked up this year, but some potential buyers hesitate, worrying about Katmandu’s frequent blackouts. In the winter, blackouts can last 18 hours a day. “Why should I buy an electric car when there is not enough electricity?” they ask him.

Bhandari’s partner, Bardan Basnet, tells them it only takes five hours to recharge. “If you can always charge a mobile phone, how bad is the power cut? You can always charge an electric car at home or another place.”

Soon he will have another selling point: Katmandu’s first solar power charging station will be installed near the REVA showroom this month. As Basnet explains: “We are trying to tell our customers, ‘Why do you need to rely on the government to power your car? You can make your own electricity!'”

What happens when Asia’s ‘water tower’ dries up?

After photographing Black Dragon Lake in Lijiang, China, for eight years, He Jiaxin knows of more places where he can get the lake to mirror the majesty of its surrounding mountains than anyone else. But this year, he has a problem: The lake has disappeared.

Since its springs dried up last year, no water has flowed into Black Dragon Lake for more than 400 days. At the same time, hot weather caused a high evaporation rate, turning a large part of the lake into a play yard for children.

“I’ve never seen such a dry-up before,” He, a 36-year-old local photographer, said while staring at the parched lake bed. “It hasn’t rained in Lijiang for a really long time.”

Lijiang is hardly alone. Similar situations are happening across other parts of Yunnan province, which usually has more rain than half of China’s regions. But it has experienced extremely low rainfall for the past three years.

In the first quarter of this year, Yunnan’s average rainfall dropped by 70 percent, indicating the start of the drought’s fourth consecutive year, according to the water resources department in the region.

As national demand for Yunnan’s hydroelectricity and other products keeps rising, the region is losing one of its most abundant resources — water — to produce them. The province is scrambling to adopt measures that would ease water stress, with mixed results. Meanwhile, its fast-growing population and economy are adding more water security problems.

Already, “when we look into the annual precipitation index we use, we can see that there has been no ‘wet’ month in Yunnan in the last four years,” said Marco Gemmer, a senior adviser of the China Meteorological Administration in Beijing.

“The length and intensity of the drought is larger than we have recorded in the past 60 years,” he added.

Forecast: more extreme weather and less relief

Gemmer attributes the record drought to changed atmospheric circulation, with less water transported in 2009 from the Gulf of Bengal, where Yunnan’s rainfall is generated, being a prime example. Other reasons include a warmer climate than usual.

“The atmosphere is a complex system, and small changes can have an effect at the other end of the globe,” Gemmer explained. “Assuming that there will be further changes in the atmospheric system under global warming, we should be prepared for more unusual events in the future, which could also include extremely wet conditions causing floods or landslides.”

Meanwhile, Yunnan is losing an ally that once helped absorb such changes. To boost the local economy, the region has been replacing its natural forests with more commercial trees like eucalyptus plantings on a large scale.

As bushes and other vegetation are cleared as part of that process, forests have a weakened ability to lock in rainwater, according to a study released this year by Greenpeace. In one county of Yunnan, the report notes, water reserves close to commercial forests dried up, while 30 miles away water was plentiful because natural surrounding forests remained uncut.

So if Yunnan continues to replace its natural forests, Greenpeace warns, the region’s forestry sector will no longer be able to conserve as much water when rainfall runs low.

‘The hardest time in my life’

That’s a thing Yang Zhikun definitely does not want to happen. Living in a village without modern infrastructure, Yang’s family relies on springs for water, but because of the recent drought there has been no water flowing into his household tank for more than 20 days.

Yang explained that he has to borrow water from distant neighbors. And if rain still doesn’t come this month when the tobacco growing season begins, Yang faces a bigger challenge.

In Yang’s village of Longba, rainwater used to be sufficient to keep his mountaintop tobacco fields green. But since 2009, rain has gone missing, and Yang had to start carrying water up from a river several miles away.

Last year, the amount of water needed for irrigation was so big that everyone in Yang’s family went to help, including his teenage children and parents in their late 70s. Still, about a fifth of the tobacco seedlings he planted withered for lack of water. Replanting added more to the workload and the difficulties to make ends meet.

“That was the hardest time in my life,” the 40-year-old tobacco grower recalled. “I don’t know how to make a living if the drought continues into this year.”

Yang is not alone. On the provincial level, the drought has already baked millions of acres of farmland over the past three years, leaving many farmers with nothing to harvest.

The financial disaster has spread to businesses that trade and process agricultural goods. For instance, many rubber factories in Yunnan reportedly shut down due to insufficient raw materials. This, combined with declining revenue in other industries, has caused a direct economic loss of about $4.2 billion in Yunnan since the drought started in 2009, local media have reported.

Little water left to ‘help the nature’

There is also a national impact. Yunnan is a major Chinese herb-growing area, and its falling output drove up herb prices nationwide. The drought has also hampered China’s ability to transmit hydroelectricity from water-rich western regions to feed the country’s power-hungry manufacturing sector, most of which is in the east.

Meanwhile, the province’s forests are on high alert because of the threat of wildfires. The drought has also dried up many lakes and wetlands, causing die-offs of aquatic species and forcing survivors to live in more polluted waters.

In Fuxian Lake, a sharp water level drop has already shrunk the habitats of a type of fish that only exists there, said Duan Changqun, an ecologist at Yunnan University. He added that changes to one species will have a significant impact on the whole ecosystem.

For now, no one knows what that impact will be. A complete analysis on the effects of Yunnan’s drought is still missing, and some damage may not emerge for years.

“Yunnan is known as Asia’s water tower because many important domestic and international rivers start from here,” Duan explained. “Droughts in Yunnan mean less water flows in the downstream, sending a blow to ecosystem of other parts of China as well as South Asian countries.”

Some steps have been taken in recent years to protect Yunnan’s drought-stricken environment, such as strengthening fire prevention measures in forests. But Duan says those efforts are negligible compared with what is needed.

“The priority is given to ensuring drinking water, and then supporting agricultural and industrial water use,” he said. “Little water is left to help the nature.”

‘Why bother to plant?’

Yet even for residents, who enjoy the most support, getting water is becoming harder. Due to years-long intensive use and a lack of refilling, water levels in many reserves run low and cities like the provincial capital, Kunming, had to cut water supplies for households to four hours a day.

Empty water reserves also made villagers hesitate to continue farming. In Longba village, the number of tobacco growers is decreasing. “Villagers believe they will not be able to get enough water for their fields, so why bother to plant?” explained Duan Shaokun, a local official.

As one grower quits, then another and another, remaining growers begin to feel the pain of a smaller community — tobacco companies are not willing to subsidize water-saving technologies and invest in more efficient irrigation systems because of the limited scale there, Duan Shaokun says. And villagers themselves can’t afford the hefty upfront investment.

So the government in Yunnan moved in to help. Through 2015, multibillion-dollar investment will be poured into constructing new water reserves of 3 billion cubic meters — a nearly 30 percent increase in Yunnan’s 2009 capacity. But experts say this may still not be enough.

“Yunnan is facing a structural challenge,” said Gemmer, the Meteorological Administration senior adviser. “The current development and economic structure cannot be maintained because it will be impossible to protect all 45 million citizens of Yunnan from droughts.”

The region’s population already increased by 12 percent and economic output per capita quadrupled since 2000, but the available water resources per capita have dropped by half, Gemmer added.

Adaptation gets harder

Yunnan has been trying hard in recent years to overhaul its resource-intensive economy and turn to industries that use less water, but now that plan is at risk.

Lijiang, for one, has bet its economy restructure on tourism. In 2010, millions of travelers came to experience its beautiful lakes, gorges and snow-capped mountains, bringing revenue of more than $1.8 billion. But with a changing climate and persistent drought, that’s gone, too.

“I wouldn’t have had time to talk with you at this time in previous years, but now I waited here for hours and saw only a few visitors,” said He, the photographer who makes a living by taking pictures for tourists near Black Dragon Lake.

Lijiang is now building a channel to bring in water from a nearby water reserve, but this can only refill part of the lake. Worst of all, global warming is causing glaciers, which supply most of Lijiang’s water, to melt faster.

According to a recent study by the Meteorological Administration, glaciers in Mount Jade Dragon began retreating in the 1980s, and more than 70 percent of glaciers there are expected to disappear if the average temperature rises more than 1.6 degrees Celsius from now to 2050.

“Glaciers in Mount Jade Dragon are a lifeline for Lijiang,” He said. “If they disappear, so will this city.”
